In my opinion, you can go for chemistry.

After doing BSC chemistry there is a lot of jobs opportunity like chemical labs . As compared to physics and bio. A lot of govt jobs also requires BSC with chemistry.

• BSC physics has lesser scope than chem.
• In my priority order

Chemistry> physics> biology

• If you want to do a job oriented course then you should go for MBBS after clearing neet. I know it takes time to clear neet. Please think for MBBS from a govt College. It costs very low as compared with private college but after 5–6 years you'll in a better position.
• Otherwise you can go for BSC chemistry. It's beneficial for both job and research perspective. If you didn't learn maths in intermediate then you'll suffer in UG and PG because UG with physics is nothing without maths. Even in chemistry also you'll have to gain good maths concept clearing. Basically physical chemistry requires mathematics.

You can choose any path :-

BSC chemistry+ msc chemistry+pgt =teacher

BSC chemistry+ prep for govt job= govt job.

BSC+msc+UGC net = assistant lecturer

BSC+msc +PhD= lecturer

Hope this helps.

Good luck.
